Blender texture baking fail
First of all, you have to check Selected to Active in Bake properties (Image below). Second, you need to have the plane, on which you want to bake the cookie UV unwrapped (go to edit mode,open UV/Image Editor window, select the texture on which you want the cookie to be baked, press U and choose Unwrap). You also need the plane to be in front of the part of the cookie, that you need to be visible. So in this case, on top/in front instead of bottom/back. Then you need to make sure, that in Distance property you have appropriate number. Looking on your scene, I think that 1-2 would be enough. Next, in object mode, you need to select cookie, then Shift select the plane and press Bake.That should do the job.Also if you need to bake only color, without shadows and lights, choose Textures in Bake Mode.



Here you have shown step by step, what you need to do
